HI Ben, The osg-users mailing list/forum is the appropriate place for support.
I've read your post, the code you provided and screenshots and don't really know what to make of it all. I'd guess that others will be similarly confused but what might be work and what might not be. I don't understand why you are subclassing from OSG classes for this type of work, for 3rd parties like ourselves not party to the the code in these subclasses and without any knowledge of why felt the need to do this subclassing it really kinda hard to know where you are going with this code. I couldn't spot any obvious errors in your code, but I sure wouldn't write a tool to visualize a road network in the way you have - having lots of separate scene graph objects and state will introduce CPU and GPU overheads that will prevent getting the best performance for your system. You don't mention what hardware/GL driver/OS/OSG version you are using. This is all is important when trying to track down problems. It could be that you have a buggy OpenGL driver and little to do with your own code. There isn't much we can say to help at this point as there is just way too many unknowns about your software, hardware, OS, exactly nature of the problem etc. Robert.
